Answer 1

The code you provided seems to have a few errors. Let's go through them step by step:

1. The line `program mar;` should be changed to `program mar;`. 2. The line `uses crt;` is unnecessary and can be removed. 3. The line `var F, S: integer;` is missing a semicolon at the end. It should be `var F, S: integer;`. 4. The line `k: real;` is missing a semicolon at the end. It should be `k: real;`. 5. The line `beginclrscr;` should be changed to `begin clrscr;`. 6. The line `for S := 1 to 4 do` is missing a space between `to` and `4`. It should be `for S := 1 to 4 do`. 7. The line `F := F * S;` is correct. 8. The line `k := k * (F + S);` is incorrect. It should be `k := k + (F + S);` to calculate the sum of `k`, `F`, and `S`. 9. The line `writeln('k+=', k:4:2);` is correct. 10. The line `readkey;` is correct. 11. The line `end.` is missing a semicolon at the end. It should be `end;`.

Here's the corrected code:

program mar;
var
  F, S: integer;
  k: real;
begin
  clrscr;
  F := 1;
  k := 0;
  for S := 1 to 4 do
  begin
    F := F * S;
    k := k + (F + S);
  end;
  writeln('k = ', k:4:2);
  readkey;
end;

This code calculates the value of `k` using a loop. It multiplies `F` by `S` in each iteration and adds the sum of `F` and `S` to `k`. Finally, it prints the value of `k`.
